    Description: The ingestion of microplastics has been shown for a great variety of marine organisms. However, benthic marine mesoherbivores such as the common periwinkle Littorina littorea have been largely disregarded in studies about the effects of microplastics on the marine biota, probably because the pathway for microplastics to this functional group of organisms was not obvious. In laboratory experiments we showed that the seaweed Fucus vesiculosus retains suspended microplastics on its surface. The numbers of microplastics that adhered to the algae correlated with the concentrations of suspended particles in the water. In choice feeding assays L. littorea did not distinguish between algae with adherent microplastics and clean algae without microplastics, indicating that the snails do not recognize solid nonfood particles in the submillimeter size range as deleterious. In periwinkles that were feeding on contaminated algae, microplastics were found in the stomach and in the gut. However, no microplastics were found in the midgut gland, which is the principle digestive organ of gastropods. Microplastics in the fecal pellets of the periwinkles indicate that the particles do not accumulate rapidly inside the animals but are mostly released with the feces. Our results provide the first evidence that seaweeds may represent an efficient pathway for microplastics from the water to marine benthic herbivores.

    Rote Liste und Artenlisten der bodenlebenden wirbellosen Meerestiere (2013)

    Description: 1,244 species out of nine phyla of macrozoobenthos have been evaluated for the Red Lists of invertebrate species in German North Sea and Baltic Sea waters (including the Exclusive Economic Zone). It is evident that the conditions in these marine waters are basically not better than ashore, since human impact like, first of all, demersal fishing and eutrophication as well as impact on coastal water biotopes have led to massive changes in several animal populations. 32 % of all species assessed are found in the Red Lists. However, more than half of these species are extremely rare and therefore assessed as potentially threatened. Altogether data are still insufficient for any trend analysis in more than 36 % of all evaluated 1,244 species (see high share in category „D“). Due to increases in knowledge and specific investigations on selected taxa it is expected that in a few years updated Red Lists can be provided, maybe covering the entire ecosystems of the North and Baltic Seas.
